Specification of Letters Patent.

Patented July 13, 1915.

Application led August 10, 1914. Serial No. 856,027.

T0 all 'whom it may concern Be it known that l, GEORGE A. HORNE, cit' Myinvention has for its object to provide a magazine gun which willcorrect certain defects found in this type of gun as heretoforeconstructed.

The particular objects of my invention are to improve the cartridgecut-olf and the sear lock of a tubular magazine gun, such as is setforth in the U. S. patent to A. J. Savage No. 1,019,367 of March 5,1912.

lVith these objects in view my invention consists in certain details ofconstruction and combinations of parts hereinafter' vdescribed,illustrated in the accompanying drawings and more particularly pointedout in the appended claims.

ln the accompanying drawings, Figure 1 is a vertical longitudinalsectional view of the loading and firing mechanism of a magazine gunconstructed according to my invention, the stock and portions of thebarrel and m-agazine being omitted for the purpose of clearness, andshowing the breech closed. Fig. 2 is a similar view showing the breechopen. Fig. 3 is a side elevation of the breech bolt in detachedposition. Figs. 4 and 5 are side elevations of the breech bolt, partlyin section and partly broken away for fullness of illustration, andillustrating the relation of the cooking lever and adjunctive featuresto the action bar and Sear lock. Fig. 6 is a rear end view of the breechbolt and of the action bar in engagement with the same. Fig. 7 is abottom plan view of the breech bolt and showing the action bar locksecuring the action bar in its forward position. Fig. 8 is a similarview showing the Sear lock engaging the sear as the action bar is movedtoward its forward position. Fig. 9 is a side elevation of the breechbolt and a portion of the `action bar, the breech bolt being partly insection and partly broken away for clearness, and lillustrating therelation of the action bar, action bar lock and Sear lock. Fig. 10 is avertical longitudinal sectional rview of the breech frame and portionsof the barrel and magazine and illustrating my improved cartridgecut-olf. Fig. 11 is a horizontal longitudinal sectional view of aportion of the breech frame and the magazine and showing a top viewpartly in section of my cartridge cut-oif.

In the drawings 1 represents the receiver or breech frame, which isconnected to the barrel 2 and magazine 3 by any suitable means. Themagazine is tubular in shape and arranged under the 'barrel 2 and isprovided with the usual spring pressed follower Baby which cartridgescontained in the magazine are forced rearwardly toward the receiverv sothat they may be successively admitted to the receiver' at the propertime.

4 is an action bar of the usual type which enters the breech frame andmay be reciprocated forwardly and rearwardly by means of the usualhandle which ordinarily slides upon the magazine 3. This action rod 4may be operatively connected with the receiver in any well known manner,for eX- ample, as shown in the aforesaid patent to Savage.

A breech bolt 5 is provided in the receiver and is arranged to be movedlongitudinally and vertically by means of the action bar 4c which entersa recess 6 provided on one side of said bolt. The breech'bolt 5 when atits forward limit "of movement. as shown in Fig. 1, engages a recoilshoulder 7 formed in the upper part of the receiver. The breech bolt isprovided with a longitudinal recess in which the firing-pin 8 is mountedand said pin has a point 9 which is adapted to engage the primer of ashell and to eX- plode the latter when the trigger 10 is operated. Acooking head 11 is provided on the end of the firing pin opposite tothat having the point 9, and said head has a recess 12 for the receptionof the upper end of a cooking lever 13. The cooking head is alsoprovided with a vshoulder 14 arranged'to be engaged by the sear 15 whichis pivotally mounted in said breech bolt. The ring pin 8 is surroundedby a coil spring 16, which abuts against a shoulder 17 'on the forwardend of the firing pin, and bears against a bushing 18 at its rear end.

The cooking lever 13 is pivoted at 19 in a recess in the rear end of thebreech bolt and its lower end is adapted to be engaged by a nose 2O onthe trigger guard 21, to cock the gun when the breech bolt is unbreechedi or moved rearwardly and downwardly. As

the breech bolt is unbreeched and the firing' pin 3 drawn rearwardly bythe cooking lever 13, the sear 15 is forced into engagement with thenotch 14 by means of a spring 22.

Mounted ina suitable recess in the lower vwhich extends into the recess6 and is pivoted in the breech bolt at 25. The action bar lock 24 isheld in its normal or locked position with relation to the action rod 4,by the spring pressed plunger 23. The action bar lock 24 'may be thrownfrom normal' position by pressing the button 26, which extends outwardlythrough an aperture to the exterior of the receiver, andthe innerextremity of said button engages a rear arm 27 of the action bar lock,when the breech bolt is in its forward orv locked position.

When the triggerr 10 is Vpulled and the cooking lever is returned to itsuncooked position, the spring operated rplunger 23 is shifted to theopposite side of the pivot 25 and reversesv its action on the actionAbar lock 24, thereby tending to release the lock from its engagementwith the lug 28, mounted on the action bar. As the cartridge isexploded, the gunA recoils but the slide handle being loose on themagazine 3 kdoes not recoil to so great an extent as the gun proper,with the result that the lug 28 on the action bar 4 becomes disengagedfrom the action bar lock 24. The forward extremity of the action barlock ismoved inwardly through the action of the spring pressed plunger23 bearing upon the action bar lock rearwardly of its pivot 25, thusleaving the parts ofthe mechanism in position to be operated for theejection of ther shell and introduction of a fresh cartridge to thebarrel through the breech frame.

Thus far described, the various parts of the gun correspond with similarparts kset forth in' the before-mentioned patent to Savage.

It has been foundin practice that'it is essential to lock the'searduring the forward movement of the action bar 4 to prevent the gun `frombeing accidentally discharged. One of my present improvements isdirected to thisi feature and consists in arranging upon the upper faceofthe rear end of the sear 15, a hook 29, which, is adapted to lbeengaged by a latching extension'30 onv the rear arm 27 of the action barlock 24, during the final upward breeching movement of the breech bolt,to prevent the disengagement of the sear 15 from` the shoulder 14,providing the trigger is held while the parts are being operated, thuspreventing the discharge of the cartridge either purposely oraccidentally when` introduced tor the barrel or until the action bar ismoved to its extreme forward position and locked.

Another of my improvements vconsists in the cartridge cut-off or stop,which will now be described. The breech bolt 5 is provided at itsforward end, as in the Savage patent,

respectively, which project upwardly intoy the slot 32 and areradaptedto be actuated by the stud 31. Springs 37 are provided between the stops33 and 34 and the wall of the breech frame for pressing said stops intothe path of the cartridge column.

The operation of the cut-offs or stops is as follows: When the breechblock is in its forward position the stud 31 engages the arm 35 anddepresses the forward stop 33, thereby allowing the rearmost cartridgeof the magazine to pass. At this time, however, the stop 34 will standin the path of the cartridge column to prevent the cartridge from movingrearwardly onto the carrier, hereinafter described. When the breech boltis moved rearwardly, the stud' 31,l traveling down the slot 32, releasesthe forward stop 33 and allows it to move into the path of the cartridgecolumn to prevent the shell next to the rearmost one from coming backinto the receiver until the proper time. Further movement ofthe breechbolt rearwardlyand downwardly causes the stud to engage the arm 36 anddisengage therear stop from the rearmost shell thereby allowing therearmost shell to come backonto the carrier. In the forward movement ofthe breech bolt, the stud, engaging and releasing the arm 36, has nospecial object or function, but as soon as the stud has left the rearstop, said stop is in position to again receive the next shell, whilethe continued forward movement of the stud causes the forward stop 33 tobe depressed and release the cartridge it had been .holding Theparticular advantage in having the rear stop 34 hold the cartridges inthe magazine while the gun is ring is in they fact, that'in rapid firingit is necessary to have the rear end ofthe rearmost shell of the columnquite a distance back in the receiver, so thatI it may be quicklyengaged by the carrier for elevating the shell. In guns heretoforeconstructed, with two stops or cut-offs, Ithe shells in the magazineduring firing were held by the forward stop, and

lThis stud 31 moves in an inin rapid firing the rearmost shell in themagazine would be forced to pass two cut-oifs before it passed onto thecarrier, and this combined operation would often cause the gun to clogor jam. TvVith my improved cutoif this defect has been eliminated.

The cartridge carrier 38 is mounted on a pivot pin 39 intermediate theends of the carrier, and arranged at the right hand side of thereceiver. The carrier is operated by a part on the breech bolt in amanner similar to that of the Savage patent and the remaining parts ofthe gun and their operation are similar to the device set forth in thesaid Savage patent.

Vhat I claim and desire to secure by Letters Patent is l. In a fire arm,a receiver, a breech bolt within the receiver, a firing pin, a sear c0-acting with the firing pin, an action bar arranged to movelongitudinally of the gun barrel, an operating stud on said action barand adapted to actuate the breech bolt, an action bar lock pivotallymounted in the breech bolt and arranged to engage with the action barstud to lock the action bar against rearward movement, and a sear lockcomprising means provided upon said action bar lock adapted to engage apart of said sear during the forward movement of the breech bolt.

2. In a fire arm, a receiver, a breech bolt within the receiver, afiring pin, a sear coacting with the firing pin, an action bar arrangedto move longitudinally of the gun barrel, an operating stud on saidaction bar and adapted to actuate the breech bolt, an action bar lockpivotally mounted in the breech bolt and arranged to engage with theaction bar stud to lock the action bar against rearward movement, and asear lock comprising an extension on said action bar lock adapted toengage a part of said sear during the forward movement of the breechbolt.

3. In a fire arm, a receiver, a breech bolt within the receiver, a iringpin, a sear coacting with the firing pin and provided on its upper facewith a hook shaped part, an action bar arranged to move longitudinallyof the gun barrel, an operating stud on said action bar and adapted toactuate the breech bolt, an action bar lock pivotally mounted in thebreech bolt and arranged to engage with the action bar stud to lock theaction bar against rearward movement, and a sear lock comprising anextension on said action bar lock adapted to engage the hook part of thesear during the forward movement of the breech bolt.

In testimony whereof I aflix my signature, in the presence of twowitnesses.

GEORGE A. HORNE.
